Does anyone know if DM2400 replacement gears are available?

I plan to contact Dyna Mechatronics about replacement gears. I believe I ruined my Y axis gear during some tinkering with GRBL.

I am still getting things up and running as I don't yet have a method to interface the original controller, and I wanted to do a comparison of modern stepper drivers with the 1980's drivers.

Any info would be helpful.
